摘要:
Compositions and methods for printing on specialty media are disclosed. The methods comprise the steps of providing a fixing fluid, providing a dye- or pigment-based ink-jet ink containing an effective amount of a polyvinyl(alcohol-acetate) species, jetting the fixing fluid onto the specialty media forming a coated substrate, and jetting the ink-jet ink onto the coated substrate. Additionally, a gelled printed image on a substrate is disclosed comprising a fixing fluid containing a fixing agent and an aqueous ink-jet ink containing a polyvinyl(alcohol-acetate) species. In both the method and with respect to the image, the polyvinyl(alcohol-acetate) species used can be a known species, or one of a number of new graft copolymers containing a polyvinyl(alcohol-acetate) polymer as one of the constituents of the copolymer.
摘要:
The present invention relates to inkjet ink pigments having surface counter-ions replaced with other counter-ions with larger size and/or hydrophobicity. The effect of the replacement is to decrease pigment-ink-vehicle-separation in the inkjet ink printing process.
摘要:
The present invention relates to an ink-jet ink comprising an improved black-to-color bleed control agent in color inks having better decap properties. The improved bleed control agent comprises a multivalent salt of a perchlorate anion. A method of using the ink-jet ink is also provided. The method comprises formulating the color ink-jet ink with the improved bleed control agent and applying the color ink-jet ink adjacent to a black ink-jet ink on a paper substrate. A method of improving decap of an ink set without affecting color-to-black bleed control is also provided.
